Recapitulation of the distribution of the enrichment in As and Sb for the various formations or sediments studied here. Four situations have been distinguished, numbered 1 to 4. Two of them, namely, situations 2 and 3, are discussed as possible marks of Fe/Mn shuttling or cold-seep influences, respectively.
Récapitulation de la distribution des enrichissements en As et Sb pour les différentes formations ou sédiments étudiés ici. Quatre situations ont été distinguées, numérotées de 1 à 4. Deux d’entre elles, à savoir les situations 2 et 3, sont envisagées comme des signatures possibles d’influences de transfert par adsorption via les particules de Fe/Mn ou de suintements froids.
| Situation 1 | Situation 2 | Situation 3 | Situation 4 |
